Just bought and converted old keg to keggle. I have been doing extract kits for 2 plus years without issue and always do the 2-3 galloon boil start in my little 5 gallon kettle. Now, I have the Keggle and would like to start doing Full volume boils.
My question is what should my beginning Boil amount be for water before boil off? 5gallon batch of beer, should I start with 7 gallons of water and assume i will get 2 gallons of boil off over my 60 minute boil?
If there is a number everyone uses on FVB, I would love to know. I would like to not have to put any water in to bring it to my 5 gallon volume at the end of the boil.
Brewing a Milk Chocolate Stout tomorrow morning for Fathers day.
